4-Methylumbelliferyl-N- acetyl-β-D- galactoside by Molecular Depot is a 4-methylumbelliferyl-N-acetyl-β-D-galactosaminide, a fluorogenic substrate for N-acetyl-β-D-galactosaminidase. The glycoside is non-fluorescent until the enzyme cleaves it, which releases 4-methylumbelliferone, a strongly fluorescent compound detectable at far lower concentrations than a coloured product. It is used as a substrate in fluorometric N-acetyl-β-D-galactosaminidase assays, in microbial identification media and in lysosomal enzyme activity testing. Each unit contains 50 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
